To aZ Z whom it may concern: I to compress the beater L the strongest at a I I96 it known that I, JOHN \V. HAMILTON, a point between the ends thereof. citizen of the United States, residing at Spring- It will be readily seen that the longer the field,in the county of Clark and State of Ohio, arm M the greater the leverage obtained by 5 have invented certain new and useful Imthescrew-threadedpieceOandthemorefirmly provements in IVashing-lviachines, of which the heaters are held in their sockets. The the following is a specification, reference beshape of the heaters is not limited to that ing had therein to the accompanying drawshown, but may be of any convenient form. 3 In Fig. 4 the inner ends of the arms M are [0 This invention relates to certain new and engaged by a flange on a nut P, turning on a useful improvements in washingmachines, screw-threaded extension D of the axle D beand the object is to provide a simple means low the arms 13. By this means all the arms of securing the boaters in the revolving head M are uniformly depressed by the flanged nut thereof, the peculiarities of which will be P. The preferred form, however, is by the 15 more fully described, and pointed out in the set-screws O, as by this means each clamp can claims. be adjusted independently of the others.

In the accompanying drawings, forming a While I have shown and illustrated the part of this specification, and in which like clamp in combination with the revolvinghead reference-lettersindicate correspondingparts, of a washing-machine, I do not wish to limit 20 Figure 1 represents aplan view of the revolvmyself to this use or form, but may apply ing head and the shaft thereof in section; Fig. it to other machines having sockets which 2, a section on the line 00 a: of Fig. 1; Fig. 3, a are to be diminished in size. Thus it will be perspective View of the hinged portion formseen that by this simple and effective aring a clamp or bent lever, and Fig. 4 a modirangement of a plate forming a part of the 2 5 fication showing another way of operating the socket and having an extension by which the clamps. leverage is increased and a bent lever formed The letter A designates the skeleton frame with said plate, whereby the beaters may be of the revolving head having arms B radiatfirmly secured in the sockets, any shrinkage ing from the hub C, in which the central shaft or play is readily taken up, and the beaters 0 D is secured bya pin extending through said are easily and cheaply replaced in case of hub or by other suitable means.

A clamp consisting of a plate that forms oted or hung to a projection K on the arm B, a part of a socket and an arm integral with so as to swing inward about the point K as a said plate and forming therewith a bent le- 0 center or fulcrum and reduce the size of said ver, and a projection supporting the plate in socket. The plateI is corrugated or grooved, the said socket and acting as a fulcrum for so as to firmly hold the heaters L, which are the lever. A preferably made of wood, in their adjusted 2. The combination, with a skeleton head positions. The plate I has an extension or and sockets in said head,of boaters adjust-ably arm M, extending under the arm 13 and ensecured in said sockets, aside portion of each gaging with a screw-threaded piece O, so as socket pivoted so as to swing inward and to be depressed thereby andcause the plate reduce the size of said sockets, and means to adjust said port-ion so as to secure said heaters.

The combination of a skeleton head having radiating arms, a, socket in the end of each arm having a slot in the side thereof, a clamp having arms and supported in the slot and fnlcrnmed so as to form abent lever, a screw-tiweaded piece acting on one arm of the level, and centers fitting said sockets and gripped by said clamps.

In testimony whereof I affix my signature in presence of two witnesses.
